Abstract
A modular parts surface treatment system includes a number of modular units each having integral conveying means for transporting the parts through the unit and delivering them to the next unit. The system includes a single modular cleaning unit, preferably for dry, mechanical cleaning of the parts. The modular cleaning unit reciprocates along a set of tracks to deliver cleaned parts to each of several side-by-side modular treatment units which tumble the parts in a bath of treatment solution and then drain them before discharging them onto the conveyor of a modular transfer unit. The modular transfer unit delivers the parts to a modular rinse unit having an inclined conveyor submerged at one end in a tank of rinse water. This conveyor transports the parts through the rinse water and lifts them above the rinse water for draining. If needed, the parts may be passed through a second modular rinse unit, or through a modular additional surface treatment unit, which may be similar to a modular rinse unit or to the modular treatment unit, and then through a second modular rinse unit. Finally, the parts are dried in a spin dryer or dry heated by air on an in-line conveyor unit.
